Hello, when can you know if you are pregnant a few days later? The earliest is how many days you can know

Patient's question:

Hello, when can you know if you are pregnant a few days later? The earliest is how many days you can know

Doctor's answer:

It is recommended to use an ovulation test kit two weeks after cohabitation to check if pregnancy can be detected. If necessary, you can go to the hospital for an ultrasound examination. Generally, early pregnancy test kits can detect pregnancy about 10 days after the fertilized egg implants, but it is usually more certain to wait until around 20 days for a reliable measurement. Changes in the body can be self-detected for pregnancy: generally, around 10 days, the breasts may become swollen and painful, and nausea may occur.
Recommendation: It is recommended that you use an early pregnancy test kit around 10 days to check for pregnancy.
